Peritoneal Malignancies
While this is a relatively rare type of cancer, Mount Sinai surgeons are experienced at diagnosing and treating peritoneal cancer.
About Peritoneal Cancer
While it takes place in the general region of the stomach—the peritonea makes up the cells that form the lining of the abdominal cavity—it’s not stomach cancer. Peritoneum is the tissue membrane that forms the lining of the abdominal cavity and covers most of your abdominal organs. Your peritoneum consists of a layer of mesothelium cells and a thin layer of connective tissue. This membrane performs the job of producing a fluid that helps organs move smoothly inside the abdomen. The disease develops when cancers of the appendix, colon, ovaries or other organs spread to the peritoneum and cause tumors to grow.
Mount Sinai surgeons are at the forefront of treating peritoneal malignancies, and we have extensive experience evaluating and treating this condition. While we may treat you with intravenous chemotherapy plus surgery, we may also incorporate heated intraperitoneal chemotherapy for a better outcome. In fact, Mount Sinai is one of the most experienced HIPEC programs in the country, having performed more than 500 adult HIPEC procedures since the program’s creation in 2007.
Procedures we perform
We offer surgical treatments for the peritoneal malignancies that we carefully tailor to meet your individual needs, such as:
- Cytoreductive surgery and heated intraperitoneal chemotherapy (HIPEC)—may include a bowel resection, splenectomy, and removal of the peritoneal lining. We target any remaining cancer nodules by infusing heated chemotherapy.
- Laparoscopic HIPEC—removes the peritoneal lining using minimally invasive surgery.
